Nikon Z mirrorless roadmap 2018-2019

I know it is still too early to talk about the future Nikon Z mirrorless roadmap since the camera is not even officially announced yet, but here is a preliminary report coming from a reliable source:

2018:

2 cameras and 4 lenses: Nikon Z6 + Z7 with the 24-70mm f/4, 50mm f/1.8 and one more wide angle lens (24mm f/1.8 or 28mm f/1.8 or 35mm f/1.8). The Z-Noct-Nikkor will be announced later - maybe at Photokina.
